What you may not know is, turkeys (like most avian species) have BARORECEPTORS. What fun, allows us to apply some PHYS! Assuming blood pressure regulation by aortic baroreceptors in birds is operationally similar to what we see in humans (it is), how would Tom the Turkey's hemorrhage be expected to IMMEDIATELY affect the activity of his baroreceptors?
a. Tom's baroreceptors would increase their rate of firing to all medullary cardiovascular center cell types. b. Tom's baroreceptors would increase their rate of firing to cells in his medulla oblongata (i.e. the Cardiovascular Control Center). In turn, this would cause an increased sympathetic discharge to his heart and an increased parasympathetic discharge to his veins and arterioles. c. Tom's baroreceptors would decrease their rate of firing to cells in his medulla oblongata (i.e. the Cardiovascular Control Center). In turn, this would cause an increased sympathetic discharge to his heart as well as to his veins and arterioles. d. Tom's baroreceptors would decrease their rate of firing to cells in his medulla oblongata (i.e. the Cardiovascular Control Center). In turn, this would cause an increased parasympathetic discharge to his heart and an increased sympathetic discharge to both his veins and his arterioles. e. A hemorrhage would not affect the activity of Tom's barorecepto
